US Market turns its head, bounces

It started with another stomach-turning drop at the open, and a loss of more than 300 points by midday. Then stocks changed course, raced higher and closed with a dramatic gain of nearly 300.

This wasn't just volatility. This was Wall Street whiplash.

Amid tumbling housing prices, an ongoing credit crisis and growing fears of a recession, turbulence has become a hallmark of Wall Street in recent weeks. And after five straight days of pullbacks, analysts saw some positive signs in Wednesday's trading.

Investors certainly found a reason to buy, perhaps encouraged by the Federal Reserve's unprecedented 0.75-point interest rate cut a day earlier and a widely held bet on another half-point cut next week.

By day's end, the Dow had swung 631.86 points from its low point to its high -- the largest single-day turnaround in more than five years.
